Cloudflare MCP Server — Explainer

What it is

A repository containing several MCP servers — small programs that let AI assistants (like Claude or Cursor) talk to Cloudflare's services using natural language. MCP (Model Context Protocol) is a standardized way for AI models to exchange context with external systems.

What it does

These servers let an AI assistant read your Cloudflare account configuration, process that information, make suggestions based on it, and even apply those changes for you. This works across Cloudflare's products, including application development, security, and performance tools.

How it works technically

• Each server exposes a stateless HTTP handler at the path /mcp (built with a fresh SDK v2 server factory).
• The old /sse URL is retired — it now answers every request with a 410 Gone error that points to the new /mcp URL, so MCP clients show that message when they try to connect.
• Modern (2026) and stateless (2025) requests share the same request-scoped implementation — there's no persistent MCP protocol session.
• Things like OAuth, credentials, account selection, application caches, and product Durable Objects remain as application/security state where needed.

Two categories of servers

1. Cloudflare API MCP Server (recommended, hosted at mcp.cloudflare.com, maintained in a separate repo cloudflare/mcp) — best for broad access across many Cloudflare APIs through code execution; uses a smaller set of general-purpose tools.
2. Domain-specific servers (in this repo, hosted at *.mcp.cloudflare.com) — best for curated, typed tools for a specific product area; more guided interactions; ideal when you work primarily within one Cloudflare domain.

How to connect

Connect any MCP client that supports remote servers directly to a URL from the table above. Cloudflare AI Playground also accepts server URLs in its interface.

Using with OpenAI's Responses API

You need an API token with the scopes (permissions) required for that specific MCP server. Example: to use the Browser Run server with OpenAI, create an API token in the Cloudflare dashboard with the appropriate permissions (screenshot in README shows the exact settings).

Troubleshooting

If you see "Claude's response was interrupted...", Claude likely hit its context-length limit mid-reply — most common on servers that trigger many chained tool calls (like the observability server). To reduce this:

• Be specific and keep queries concise.
• Break one large request into several smaller tool calls.

Paid features

Some features may require a paid Cloudflare Workers plan — make sure your account has the necessary subscription level.
